ACETYLENELAMP BURNER TIP.

Application filed June 29, 1920.

To all whom it may concern. 7

Be it known that I, LoU1s E; PoLHEMUs, a citizen of the United States, residing at Miami, in the county of Gila and State of Arizona, have invented certain new and useful Improvements in an Acetylene-Lamp Burner Tip; and I do hereby declare the fol lowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of the invention is to provide a simple and eflicient burner tip which can be manufactured at a small cost for use in connection with acetylene hand lamps and the like, and more especially to provide a tip for the purpose indicated which can be constructed of metal such as brass, lead, zinc, pewter or the like which will act as an efficient and economical substitute for lava and like materials heretofore employed in this connection and regarded as necessary if not indispensable with relation to lamps of the type indicated, and also to provide in this connection means for effecting a practical and convenient seating of the tip in the burner or burner tube and for disposing of the moisture which is the result of combustion or condensation at the point of ignition; and with these objects in view the invention consists in a construction and combination of parts of which a preferred embodiment is shown in the accompanying drawing, wherein:

Figure 1 is a side view of a burner tip embodying the invention applied in the operative position to a burner tube, the latter being shown in section.

Figure 2 is a sectional view taken in the plane of the axis of the tip.

Figure 3 is a front view of the burner ti Figure 1 is a sectional view showing a modified means for securing the proper joint between the nipple of the burner tip and the burner tube.

The burner tip embodies a conical recess or basin 1O intersecting at its apex with a channel 11, which may be of cylindrical form, constituting the bore of a nipple 12 which may as illustrated in Figures 1, 2 and 3 be of slightly tapered form, to adapt it to be fitted in a burner tube or seat 13, the ta pered exterior contour of the nipple being such as to adapt it to slight variations in the diameter of the seat and permit it to be Specification of Letters Patent.

forced into joint. I

A modification of this feature of construction is shown in Figure 4 wherein the nipple 12 is fitted with a con'ipressible sleeve or jacket 12 of rubber or equivalent material, to efiect the proper seating of the burner tip and hold the same against accidental displacement while insuring a gas tight joint.

The body portion of the tip is represented by a disk 13 which is disposed ina plane perpendicular to the axis of the nipple 12 and is preferably peripherally milled as shown at 14 to provide a grip, so as to facilitate the turning of the burner tip in effecting a snug and practical seating of the nipple in the burner tube.

The face of the burner tip embodies an annular tip 15, surrounding the conical recess or basin 10 and provided in its forward position to effect a gas tight edge with a drain groove 16 adapted to re ceive moisture formed on the lip and convey it around the cavity or basin so that it may escape at the lower side thereof. Also formed in t e face of the tip surrounding the lip, and at the base of the latter is an annular gutter or drain channel 17 for a purpose similar to the groove 16 and designed to prevent moisture which may be incident to the combustion of the gas at the point of ignition, from interfering with the flame by impeding the progress of the gas or obstructing the cavity or basin through which the gas passes as it expands after leaving the minute burner orifice 18 formed as above indicated by the intersection of the cavity or basin at its apex with the transversely disposed end wall 19 of the, channel or passage 11.

A burner tip constructed as described can readily be either cast or moulded or stamped, and therefore itcan be constructed at a minimum cost of materials which are of a relatively low or moderate value as compared with those which heretofore have been regarded as necessary in the construction of burner tips subjected to the intensity of heat incident to the combustion of acetylene gas.

Having thus described the invention, what I claim is:

1. A burner tip of the class described having a body with a duct for passage of gas, a

manipulating portion extending from the body, a tip portion extending from said portion and having an endless passageway at the point of connection therewith, said tip portion having an endless passageway in its outer face and also having an opening with an outwardly flared wall leading directly from the duct.

2. A device of the class described having a body with a duct for the passage of gas, a

tip having a conical outer wall, a manipulating portion projecting laterally beyond the tip, said manipulating portion having a groove forming a passageway at the junction with said tip, and the wall of said groove merging with the said conical wall.

3. A device of the class described having a body with a duct for the passage of gas, a manipulatlng portion extending from the gas conducting portion; a tip extending from signature
